Seattle "living building" sports green roof, solar array

The 50,000-square-foot Bullitt Center in Seattle will showcase its features that meet the Living Building Challenge standards on Earth Day, April 22. Dubbed the "world's greenest building," the facility sports a green roof, along with cisterns that will manage stormwater runoff at the site. The six-story building also has a solar array as its source of energy, and architectural features that make its interior healthier for its occupants.
